Solar storm warning system and who should end signals to aliens?

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - The Earth has vast oceans and large glaciers near its poles, yet less than one percent of our planet's mass is locked up in water. A new analysis is helping astronomers understand why the Earth is comparatively dry. See article.
g Message - Recent discussions within the SETI community have thoroughly explored the issue of whether people with access to radio telescopes should send powerful signals to alien civilizations without some process of prior international consultation. In particular, those exchanges have focused on the question of "Active SETI." See article.
g Cosmicus - Massive explosions on the Sun can unleash radiation that is dangerous for humans and robotic missions in orbit. Now, researchers have developed a warning system that can forecast the radiation from these storms up to three hours in advance. See article.
